My lawn mower blades get dinged up real good by sticks and small rocks.
Grinding them takes me a long time, 2 blades, 4 edges.
Is there any reason why I couldn't set up the angle in the mill
and clean them up with an end mill?
I would think this would be a lot faster.
I could always grind in the final edge.

If this isn't a good idea, then everyone should forget I asked a stupid
question.

It will probably work, but I can't see it being fast.

Try an angle grinder and discs rather than a bench grinder. Works way
faster for me.

Yeah, I've used both, but now I only use a little 4" angle-head grinder. The
wheel isn't quite as cool-cutting as a coarse wheel on a bench grinder, but
it's so much easier to hold the right angle, and to see what you're doing,
that the job goes much faster even though you have to let the blade cool
after every few passes.

Not that the stuff they make blades out of is likely to suffer from some
overheating, but I just hate to see that blue color on steel while I'm
grinding it.



There's no need, or use, in getting every nick all the way out - you go
mow, there will be new nicks.

Belt grinder would probably also work faster.
